We look at the division of 48138538 by 489 
Our goal is to divide 48138538 by 489.

Advancing to step 1:
The number 489 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 489

Advancing to step 2:
The number 489 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 489

Moving on to step 3:
The number 489 fits into 481 0 times, leaving a remainder of 481.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 481, we end up with 481.
Fetch the next digit (3) from the dividend, attach it to 481 and continue: 4813 / 489

Going ahead to step 4:
The number 489 fits into 4813 9 times, leaving a remainder of 412.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 4401 from 4813 leaves us with 412.
Fetch the next digit (8) from the dividend, attach it to 412 and continue: 4128 / 489

On to step 5:
If we divide 4128 by 489, we get 8 and a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 98.0
The remainder is 216 after subtracting 3912 from 4128.
Append the next digit (5) from the dividend to 216 and continue with: 2165 / 489

Let's proceed to step 6:
If we divide 2165 by 489, we get 4 and a remainder of 209.
Use 4 as the next digit of our solution. 
Result so far: 984.0
If we subtract 1956 from 2165, we get 209.
Take the next digit (3) from the dividend and append it to 209, then repeat: 2093 / 489

Let's proceed to step 7:
If we divide 2093 by 489, we get 4 and a remainder of 137.
The next digit of our result is 4. 
Result so far: 9844.0
Subtracting 1956 from 2093 leaves us with 137.
Fetch the next digit (8) from the dividend, attach it to 137 and continue: 1378 / 489

Step 8:
If we divide 1378 by 489, we get 2 and a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 98442.0
If we subtract 978 from 1378, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 9:
The number 489 fits into 4000 8 times, leaving a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 98442.8
Deduct 3912 from 4000 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 10:
489 can be fit into 880 1 times, resulting in a remainder of 391.
Use 1 as the next digit of our solution. 
Result so far: 98442.81
Subtract 489 from 880 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 11:
When dividing 3910 by 489, we get 7 with a remainder of 487.
Use 7 as the next digit of our solution. 
Result so far: 98442.817
If we subtract 3423 from 3910, we get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Going ahead to step 12:
4870 divided by 489 is 9 with a remainder of 469.
Put 9 as the next digit of the answer. 
Result so far: 98442.8179
If we take 4401 away from 4870, we end up with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Step 13:
489 can be fit into 4690 9 times, resulting in a remainder of 289.
The number 9 becomes the next digit in our result. 
Result so far: 98442.81799
Subtracting 4401 from 4690 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

The final result is 98442.81799 with a remainder of 0.000289.
